You’ve started building a nice selection of applets here, and work seems to be ongoing; the “Vector calculator” page includes the statement, “We’re still ironing out the kinks in the code, so bear with us for the moment!” I look forward to seeing more of this work as it progresses.

I write similar applets that may be of interest to you and your readers:

Presently, JavaScript programs are posted that solve N Equations in N Unknowns, compute Eigenvalues and Eigenvectors of a real general matrix, and perform a Cholesky Decomposition on a real symmetric matrix, to name a few. Source code is viewable (I have done nothing to obfuscate the JavaScript code; furthermore, C++ source code for the programs is being posted on GitHub.) Several more programs are in the works and I am open to suggestions as to what other sorts of discrete math applets could be written that would be useful.

]]>–Collatz Odd Number Calculator (with Factors and Graphing)

–Goldbach “Stress Test”

–Legendre’s (Linear Parity)

–Legendre’s (Fractional Elimination)

These are macro-enabled worksheets (enable content, enable macros).
